Beware of location services
Many apps on iPhone and Android use “location services” to, say, tag status updates with GPS data (“We’re at Disney World!”) or find good deals in your immediate area. This can reduce battery life, so always keep track of it. You can tell if an app is using location services by looking out for a small arrow on the top of your menu bar. Lifehacker has a thorough set of instructions for turning off this feature.
Watch for push notifications
How much battery life is drained by push notifications, those app-specific messages that pop up on your lock screen from time to time? That’s up for debate, but consider this: Each time your phone receives a notification from the network, it lights up and, depending on your settings, vibrates or makes a noise, too. That all takes a toll on your battery, especially if you receive a lot of updates. Toggle push notification options in your settings screen or within the apps themselves to remove all but the vital stuff. These are the 10 cell phone etiquette tips everyone should follow.
